Two further sine waves emerged in 2002, corresponding to one planet that has the mass of Saturn and is also orbiting more closely than Mercury, and another with four times the mass of Jupiter that is located in what would be Jupiter's orbit.
An international team of researchers said the so-called protoplanet has a mass that appears to be at least the size of Jupiter, and perhaps two to three times larger.

Using these two instruments, the scientists were able to examine the event and determine that the mass of the planet being devoured by the black hole was somewhere between 14-30 times that of Jupiter.
